A STB is definitely the easiest for starters imo...
This link is pictorial I used for my first extraction. It worked like a charm.
An A/B is the next runner up and will typically pull prettier, whiter spice. Yields are comparable to a STB unless you want the funky jungle that the xylene affords and then the STB comes out on top.
There are plenty of other teks, but the link I gave is a good start.
Good luck and be safe!
